Many generations ago, Sonogong, a 300 year old being, was the lone survivor of an attack on the village he vowed to protect. The leader of that attack only wanted Sonogong's great power for himself, but Sonogong would not bow before anyone. He was then sealed for 1500 years to prove to him that the world humans would bring forth wasn't worth protecting. When Sonogong awakens...what will he think about the society humanity has birthed? What if he doesn't like it?
